What is a common approach corrupted private police would use in the criminal courts?

Corrupted private police might use several approaches in the criminal courts, including:

1. Bribery: This is one of the most common methods used by corrupt private police. They might bribe court officials, judges, or even the prosecution to sway the case in their favor.

2. Tampering with Evidence: Corrupt private police might manipulate or destroy evidence that could potentially incriminate them. This could involve anything from altering documents to planting or removing physical evidence.

3. Intimidation or Threats: They might use threats or intimidation to influence the testimony of witnesses. This could involve physical threats, blackmail, or other forms of coercion.

4. False Testimony: Corrupt private police might lie under oath to protect themselves or their associates. This could involve making false statements or denying involvement in criminal activities.

5. Collusion: They might collude with other corrupt individuals within the system to ensure their activities go unnoticed. This could involve working with corrupt prosecutors, judges, or other law enforcement officials.

Please note that these are illegal activities and are heavily punishable under the law.
